Asbestos in ceiling?

[Beansbaked]

Hi, we live in a ex council house built late 1940-1950s. It has a coal shed/ toilet built on the side. The roof is flat, there’s no corrugated sheeting. The roofs been leaking and a huge part of the ceiling fell away It left behind what looked like a mortar mix and a metal grid. There was some visible white “hairs” about an inch long, almost like cat hair. The leak and the ceilings been fixed but since googling I’m wondering if it was likely to have contained asbestos in the mortar mix? I’m really worried as we did this ourselves as a diy project. I know it was a stupid idea.

Only way to know is to get a sample tested. Plenty of companies offering that service. May as well do it and know for next time. But if it's all now sealed / covered up, then there is no point going back in at this stage.

Thank you, a builder came out last week and re boarded and plastered it. I’m worrying myself sick over it though I know there’s nothing that can be done

Unless you were face into it with a grinder, drill etc with dust flying everywhere, there's almost no risk.

Thank you for your reply. Unfortunately once the first part fell away we used a hammer to break more away thinking it would be easier to fix with it all gone. No masks just 2 very silly people. Took about an hour and a half all together. There wasn’t a huge amount of dust in the room no where near what you would get drilling or grinding. It was quite gritty which made me call it a mortar but maybe I’ve even got that wrong

I'd say for sure this is animal hair in the plaster undercoat. Probably a sand and lime mix, which would have been quite coarse. Horse hair was often added into old plaster and render mixes to stop it cracking. Sometimes other animal hair was used - cow, goat, dog or even llama, apparently. An inch long would be the ideal length.

Thank you for your reply. Where the plaster/mortar or whatever it is split I could see the white hairs. They didn’t look clumped together like I would expect them to be they looked like single hairs which makes me think more it’s asbestos.

The animal hair would be teased apart before adding to the mix. I don't think asbestos fibres are anything like that long - more like microns (thousandths of a millimeter), which is why they float about unseen in the air.

Thanks again for your reply. I also read about asbestos fibres being so small you couldn’t see them but in my search today I read it can be seen in the edges of plaster, which has send me completely spiralling about it. I feel sorry for my poor husband. I know without testing we can’t be sure but I was hoping people who work with this daily might be able to ease my worries a little. 
 

The identical house next door had this area made into a wet room about 10 years ago through the nhs and nothing was mentioned about asbestos that we know of. They would have had new lights put in I wonder if their builders would have found it or would they not have taken as much of the ceiling down as we did

Cut out a small section having sprayed it with shaving foam*, then as the board comes away, spray liberally with water, take sample, send off, box up.

 

I, too, have never seen asbestos fibres as long hairs. I suspect you will find those are from an animal, but until you know it is unlikely to stop you worrying. I have been in this position. Expose a little of the offending material - ever-so-carefully, as explained - send off a sample and get clarity.

 

* The shaving foam is not as ridiculous as it sounds. HSE do, or at least used to (I have not checked lately) have it as a way of containing fibres, particularly for suspected asbestos cement soffits.
